President Donald Trump faces a pivotal week as he plans to roll out his most significant round of tariffs, while elections in Wisconsin and Florida could serve as an indication of how voters feel about the opening months of his second term.

Last week, Trump announced he was pulling New York Representative Elise Stefanik's nomination to be U.S. ambassador to the United Nations , saying it is "essential that we maintain EVERY Republican Seat in Congress ."

The withdrawal reflected concerns that the GOP's slim majority could be further eroded ahead of two special elections in Florida, which could derail efforts to enact Trump's agenda in the coming months.

This week's elections come as Trump has promised that Wednesday will be "Liberation Day" as he plans to unveil tariffs that he says will free the United States from foreign goods. He is forging ahead even as his growing list of tariffs and their stop-start implementation has sparked stock market volatility and raised concerns about a looming recession .

Newsweek has contacted the White House for comment via email.

Florida Special Elections

Special elections are taking place to replace Florida's Republican former Representatives Matt Gaetz and Michael Waltz, now Trump's embattled national security adviser , on Tuesday.

Republican Jimmy Patronis, the state's chief financial officer, and Democrat Gay Valimont, a gun control activist, are running to replace Gaetz in Florida's 1st congressional district.

In the 6th congressional district, Republican state Senator Randy Fine and Democrat Josh Weil, a public school educator, are running to replace Waltz.

Both districts are Republican strongholds, but Democrats see strong fundraising as a sign that the races will be more competitive than they were in November. Polls favor the Republican candidates, but a tighter than expected race could be seen as evidence that the Trump administration's agenda is losing support.

Bryan Piligra, a spokesperson for Fine's campaign, told Newsweek last week that "the only thing that matters is making sure Republicans are united to defeat radical Democrats" and that when Fine is "victorious on April 1 it will be because of the strength of the Trump agenda and the faith the American people have in him."

Wisconsin Supreme Court Election

Conservative Waukesha County Judge Brad Schimel and liberal Dane County Judge Susan Crawford are vying for the open seat on Wisconsin's highest court in the April 1 election.

The ballot could change the ideological makeup of the court, which is currently controlled 4-3 by liberal justices.

The contest, which has become the most expensive judicial race in U.S. history, comes as the court is expected to rule on high-profile cases on abortion, union power, congressional redistricting and voting rules that could affect the 2026 midterms and 2028 presidential election. The court's makeup could also affect how it could rule on future voting challenges in the battleground state, making it one of the most consequential contests of Trump's second term so far.

But as the first election since Trump returned to the White House, the race will be a critical barometer of how voters are feeling about his second term in a critical battleground state.

While the seats are officially nonpartisan, Trump has endorsed Schimel while Democrats have lined up behind Crawford. Conservatives have cast it as a chance for Trump's supporters to back him once again, while Democrats are seeking to channel voter anger over billionaire Elon Musk , who is leading the administration's efforts to slash spending and the size of government.

Trump urged voters to support Schimel in a Truth Social post on Sunday, calling Crawford a "liberal lunatic" who he said would "throw our Country, and the State of Wisconsin, into TOTAL CHAOS." Derrick Honeyman, a spokesman for Crawford's campaign, told Newsweek that Trump and Musk are "lashing out" as Schimel's "record of failures catches up to him."

'Reciprocal' Tariffs

Trump has promised to unveil a massive tariff plan on consumer goods on Wednesday, which he dubbed "Liberation Day."

He told reporters aboard Air Force One on Sunday that the reciprocal tariffs he announces will include "all countries," rather than a smaller group of countries dubbed the "dirty 15."

Stock markets around the world tumbled on Monday as concerns build that the latest round of tariffs will worsen inflation and harm economies.

Most economists say the cost of tariffs will be passed along to consumers in the form of higher prices, which could cause Trump's approval rating on his handling of the economy to plummet further and potentially change his ability to win the support of Republican lawmakers and impact his ability to push through his agenda.

Trump also announced 25 percent tariffs on imported cars and certain auto parts that will also take effect this week. The tariffs are expected to have sweeping implications for the auto industry and U.S. economy. But Trump told NBC News on Sunday that he "couldn't care less" if automakers raise prices due to the tariffs "because if they do, people are gonna buy American-made cars."
